Z Anomalous Couplings and the Polarization Asymmetry in $γe \to Ze$

Abstract

We extend our previous analysis of the sensitivity of the energy dependence of the polarization asymmetry in $γe \to Wν$ to the possible existence of anomalous trilinear gauge couplings to the $γe \to Ze$ case. We find that by combining the constraints imposed by both the energy dependence of the total cross section and polarization asymmetry, strong limits on the anomalous $γZZ$ couplings are obtainable at the Next Linear Collider. Further constraints obtained from a consideration of the angular distribution are briefly discussed.
